I came across this free WP (WordPress) template maker online.

The best part?

• It’s FREE
• It’s online
• It’s got a real-time preview function

The downside:

The choices are limited

But if you’re creating a blog network and need to vary the designs or you’re a WP designer looking to create some really quick variations of a blog to sell or give away this could be perfect (please check the License first!)!
